Fuzzy logic apparatus control.

摘要

Two evaporator circuits operate a freezer compartment and a fresh food compartment. The freezer compartment runs typically at 0-2 psig evaporating pressure until satisfied. The refrigerator section that runs typically at 18-22 psig evaporation pressure. A single compressor supplies the refrigerant through the condenser which serves to feed either the high or low pressure evaporators through known expansion devices such a capillary tubes, orifices, expansion valves, etc. Although various circuit options are disclosed, each employ some type of solenoid valve at the capillary tube inlet to determine which evaporator is fed.
